If you don't, you've got to find a solution to enter each transaction on your tax return manually if you file electronically.  

Any suggestions on electronic payment system software?  

I just send electronic payment monthly to mine.

I would also make sure that the agent has an electronic system to quickly write up offers, or a team that handles writing offers.  

Regardless of whether it will be your home or an investment, everything can be done while you’re out of State.Viewings can be done on FaceTime or Zoom, same with the summary by your inspectors and any other walkthrough.Document signatures can all be done electronically up until closing, which requires notarized documents sent back overnight by mail.All funding can be wired, earnest money and closing amount, but ALWAYS confirm wiring instructions verbally with a contact person via a confirmed phone number.You just need to figure out who will hold your keys and possibly check on the property until you move in, or arrange property management and rent it out.

Electronic copy would be just as good.

., which has several PDF forms that can be filled out electronically.

I would like to explore bartering new, Major Brand current model Computer Lines (Laptops, Desktops, PDA's, & software) as well as complete lines of Consumer Electronics (Flat Screens, TiVo, MP3 +++) in exchange for a single family residence in the $250-$500K price range.

I think the best strategy would combine both physical and electronic options.

Could hire a payment/note processor and do it all electronically for a fee or go neolithic and have the seller open an account at a bank with a branch near your house and you deposit your payment to his account every month.
